Effective treatment of dyes wastewater is important to prevent water pollution. According to data by the Department of Environment (DOE) in 2017, 51 rivers have been polluted because of sewage, industry growth, livestock breeding and attitude of some irresponsible Malaysians that dump trash into river. One of the industries that contribute to river pollution is the batik industry. This is because batik processing activities have resulted in effluents containing chemicals streamed into the river and affecting aquatic life and human health as well. The main goals of this project is to produce a filter from available locally materials in solving polluted river water arising from batik wastewater. Along with the theme “from nature back to nature”, PadS-Clay Filter were prepared from 100% waste material such as paddy straw and clay according to designed formulation. Then, the dyes wastewater was flow on the PadS-Clay Filter and passed through the filter. The UV-Vis spectrophotometer was used to analyze the absorption and concentration of the filtered dyes wastewater. Based on the result, PadS-Clay 2 (PSC2) and PadS-Clay 3 (PSC 3) were the most effective designed formulation for dyes rejection and flux of dyes in treating dyes effluent as the percentage of the dyes rejection for all PSC2 were over than 90%.
